Lunchtime Links: Junior prom in Massachusetts shuts down due to pot brownies

School officials shut down the North Andover High school's junior prom over the weekend after several students became violently ill. Authorities discovered that the students had eaten some marijuana-laced brownies.

"In the course of the investigation, it was determined that 19 brownies had apparently been distributed by a student earlier in the day before arriving for the evening at the high school," said North Andover Superintendent Chris Hottel.
